You can place Slider or any class that does not have .usc description by using "User class" and typing the class name manually.

Sure, .usc description would be useful as well, but right now is not top priority. Maybe the community could help with .usc scripts (it really is not that complicated).

Here is an update of CtrlLib.usc for SliderCtrl

ctrl SliderCtrl {
	group "Progress";

	GetMinSize() { sz = GetTextSize("X"); sz.cy += 2; return sz; }
	GetStdSize() { sz = GetMinSize(); sz.cx *= 7; return sz; }

	Frame  SetFrame @1;

	Paint(w) {
		r = GetRect();
		
		sz = Size(r.right - r.left, r.bottom - r.top);
		
		if (sz.cx < sz.cy) {
			halfX = sz.cx >> 1;	
			halfY = sz.cy >> 1;
			DrawInsetFrame(w, Rect(halfX - 2, 2, halfX + 2, sz.cy - 2));
			imgSz = GetImageSize("CtrlImg::vthumb");			
			w.DrawImage(halfX - (imgSz.cx >> 1), halfY - (imgSz.cy >> 1), "CtrlImg::vthumb");
		} else {
			halfX = sz.cx >> 1;	
			halfY = sz.cy >> 1;
			DrawInsetFrame(w, Rect(2, halfY - 2, sz.cx - 2, halfY + 2));
			imgSz = GetImageSize("CtrlImg::hthumb");			
			w.DrawImage(halfX - (imgSz.cx >> 1), halfY - (imgSz.cy >> 1), "CtrlImg::hthumb");			
		}					
	}
}


Could someone please add it to the main code tree ?

Thanks,
Victor

Please discard my previous message... The following code now works with Ctrl frames. I have also included a "basic" ProgressIndicator. They should be ready for integration in the main branch.

ctrl SliderCtrl {
	group "Progress";

	GetMinSize() { return Size(0, 0); }
	GetStdSize() { return Size(64, 24); }

	Frame  SetFrame @1;

	Paint(w) {
		r = GetRect();
		DrawCtrlFrame(w, r, .SetFrame);
		
		sz = Size(r.right - r.left, r.bottom - r.top);

		halfX = int(r.left + r.right) >> 1;
		halfY = int(r.top + r.bottom) >> 1;
		
		if (sz.cx < sz.cy) {
			DrawInsetFrame(w, Rect(halfX - 2, r.top + 2, halfX + 2, r.bottom - 2));
			imgSz = GetImageSize("CtrlImg::vthumb");			
			w.DrawImage(halfX - (imgSz.cx >> 1), halfY - (imgSz.cy >> 1), "CtrlImg::vthumb");
		} else {
			DrawInsetFrame(w, Rect(r.left + 2, halfY - 2, r.right - 2, halfY + 2));
			imgSz = GetImageSize("CtrlImg::hthumb");			
			w.DrawImage(halfX - (imgSz.cx >> 1), halfY - (imgSz.cy >> 1), "CtrlImg::hthumb");			
		}					
	}
}


ctrl ProgressIndicator {
	group "Progress";

	GetMinSize() { return Size(0, 0); }
	GetStdSize() { return Size(64, 24); }

	Frame  SetFrame @1;

	Paint(w) {
		r = GetRect();

		DrawCtrlFrame(w, r, .SetFrame);	
		DrawInsetFrame(w, r);
		
		sz = Size(r.right - r.left, r.bottom - r.top);
		
		w.DrawRect(r.left, r.top, sz.cx, sz.cy, :SBlack);
		DeflateRect(r);
		sz = Size(r.right - r.left, r.bottom - r.top);
		w.DrawRect(r.left, r.top, sz.cx, sz.cy, :SWhite);		

		if(sz.cx > sz.cy) {
			w.DrawRect(r.left, r.top, sz.cx >> 2, sz.cy, :SLtGreen);		
		}
		else {
			w.DrawRect(r.left, r.bottom - (sz.cy >> 2), sz.cx, sz.cy >> 2, :SLtGreen);
		}
	}
}


Writting usc is very easy... when you understand how to deal with frames Smile
